TM3DQ16TG Schneider Modicon TM3 16-Channel Digital Output Module

TM3DQ16TG Schneider Electric Modicon TM3 Digital Output Module

TM3DQ16TG is a 16-channel transistor output module from the Schneider Electric Modicon TM3 series. It switches 24 Vdc source (PNP) loads at up to 0.5 A per channel. Engineers use it for fast discrete control in compact machines.

Why This Module Stands Out

• 16 source (PNP) transistor outputs in a 27.4 mm wide housing
• 0.5 A per channel with short-circuit and overload protection
• 450 µs max. turn-on and turn-off response
• Removable spring-cage terminal block, 3.81 mm pitch
• 500 V AC isolation between output and internal logic

Oiltech Controls Review

• The TM3DQ16TG fits machine builders who need dense PNP outputs.
• Spring terminals cut wiring time on the panel.
• Per-channel protection reduces downtime after a short.
• 450 µs response suits high-speed sorting and packaging.

Oiltech Controls’s Insight

• Pair this module with M241 or M262 for mid-size lines.
• Check 0.5 A per channel against your solenoid and relay loads.
• Use 24 Vdc source wiring for PNP sensors and valves.
• Keep 27.4 mm width in mind when planning DIN rail space.

Installation Notes

• Snap the module onto a DIN rail next to the TM3 bus.
• Wire outputs with the removable spring-cage block.
• Follow 3.81 mm pitch for clean terminal layout.
• Keep 0 to +55 °C cabinet temperature.
• Respect IP20 limits in dusty or wet areas.

Diagnostics and Protection

• Module status LED shows power and health.
• Bus status LED shows TM3 bus communication.
• Short-circuit protection trips per channel.
• Overload protection prevents output damage.

FAQ

Q: Can the TM3DQ16TG drive solenoid valves directly?
A: Yes, if each valve draws 0.5 A or less.

Q: Does this module work with the M221?
A: Yes, it is compatible with M221, M241, M251, and M262.

Q: What happens if one output short-circuits?
A: That channel trips while other channels keep working.

Q: How do I choose between relay and transistor outputs?
A: Pick transistor for fast switching and long life. Pick relay for high current AC loads.

Q: Can I replace a failed TM3DQ16TG without rewiring?
A: Yes, the spring-cage terminal block is removable.
